Charts I use are 1/5/15/60/daily. I find the tick chart to be too whippy.
"primary entry chart"
All of them!
I could use any one of them alone for entry but prefer to use all together to enter, run and exit. To fine tune the entry I use a minute chart. But it is what is shown in those charts along with indicators if any, and how you 'read' what is in front of you that matters.
Of the 11 or so who don't use a chart at all - maybe they're all Nasdaq traders who use level 2 exclusively. Possible I suppose, but unlikely. This begs the question - what do they use - gut feeling, the stars, the ratio of red trafic lights vs green ones on the way to work? Answers on a post card please.
I always have the previous day's chart on view to note areas of S&P. Of particular interest are that days high/low. Having said that, I wouldn't enter a trade based purely on this set up, although I may well exit one. I'm interested in your strategy - is it based on historical data whereby you know that if the instrument you're trading breaches the previous day's high there's better than say (for arguements sake) 70% probability that it will advance another x% of the average daily trading range? Vice versa for shorts. And, if I may be so bold, can I enquire if your strategy is profitable?
the FTSE seems to have what seems to be a 3-day cycle in it, ie when there are no outside shocks (eg pesky bombs going off)
i use the high/low to gauge the current day in relation to where we should be..
for the sake of not going into the full method, if we havent had a new high for 2 days, then its time to go long, and vice versa for a short. then the market generally (approx 75% of the time) pulls itself back to roughly where it was before (depending on the trend it could be shifted a fair few points in each direction) there are other entry criteria, based on prev days range and what have you but these are staying private for a while at least.
im trading a version of this in my journal. sadly im currently long in this sell-off, which is a pain i can tell you..thought i was going to be going short tonight too, but then the late sell-off put pay to that.
in backtesting, over a 15 trade period it never had a losing period, which is what keeps me going in tricky times such as this.
